= DPBOEPSD (Assumed Exchange PSD Mask)
defines the PSD mask that is assumed to be
exchanged at CO. Use this graph to view PSD
level to frequency relationship. The horizontal is
frequency in MHz and vertical is power level in
dBm/Hz.
<epsd>: 0~255 (scalar value 0~-127.5dBm in
steps of -0.5dBm)
<psdid>: standard psd shape id for psd toolbox
0: psd_co, 1: psd_flat, 2: psd_cab_ansi, 3:
psd_cab_etsi, 4: psd_exch_etsi, 5: psd_exch_ansi
= Sets the electrical length of the cable between
system and cabinet 0~511 in units of 0.5dB.
= UPBO (Upstream Power Back-Off) mitigates far-
end crosstalk (FEXT) caused by upstream
transmission on shorter loops to longer loops.
disable: turns UPBO off.
auto: enables UPBO and CPE devices' PSD
adjustment based on the negotiation result with the
Switch.
override: forces CPE devices to use the
electrical length defined by the system (for the
UPBOKL setting above) to compute their UPBO.
= Specifies parameter A value(s) for each upstream
band. The parameter A defines the original band
shape.
<us1a~us4a>: 4000~8095, in steps of 0.01 dBm/
Hz.
Specifies parameter B value(s) for each upstream
band. The parameter B defines the power back-off
degree.
<us1b~us4b>: 0~4095, in steps of 0.01 dBm/Hz.
= Specifies the VDSL2 profile(s) used for this VDSL
line profile.
vdsl2-profile-type: The available VDSL2
profile types include 8a, 8b, 8c, 8d, 12a, 12b, 17a,
and 30a. You can specify multiple profile types by
using a comma (,) in between.
= Sets the downstream limit mask you want the
system to use.
= Specify whether you want the system to
automatically activate the upstream band
(enable) or not (disable) when necessary.
Select Allow to have CPE and the system use the
upstream band 0 for upstream traffic over long
distances. If you select disable, the CPE may not
able to transmit data over long distances.
= Select a limit mask you want the system to use for
the upstream band 0.
